CL-7 microprocessor-based voltage regulator control and accessories

GeneralEaton's Cooper Power™ series CL-7 is the latest voltage regulator control. The CL-7 control maintains the easy to use interface of previous CL controls. Advance features enable easy integration into a smart grid enabled network because the CL-7 voltage regulator control is designed with communications and smart grid features in mind. The versatile CL-7 comes as standard equipment on Eaton's voltage regulators, but easily integrates to operate nearly any voltage regulator in service today.

Familiar features

The CL-7 control employs the same easy to use features of previous CL controls. It utilizes most of the same function codes and all of the same easy-to-use interface features. Field technicians familiar with earlier regulator control models will already know how to use the CL-7 control. This translates to lower training costs.

Common platform

Eaton's common control platform means shared components and a familiar look and feel between controls. This will reduce inventory of components and lead to a distribution system that is easier to maintain. Whenever possible, items like communications cards and I/O modules are shared between controls.

Focus on smart grid

The CL-7 control is designed to integrate easily into smart-grind communications networks. Communications features are available to simplify installation include integrated communications modules, multiple protocol availability, communications battery backup, dc power supply and auxiliary ac power supply. The controls are shipped with the resident communications protocols of DNP and IEC 60870-5 and additional protocols are available upon request.

Multi-phase control

The CL-7 voltage regulator control multi-phase option is unique in the industry. It provides the first of its kind multi-phase voltage regulation: two or three regulators can be operated with the use of a single control. This provides a single point of contact for communications, true multi-phase metering and fewer controls to program and maintain. In addition, when power is lost from one regulator in a bank, the power from an adjacent regulator can be used to run the motor.

Advanced software

Eaton's Cooper Power series ProView™ NXG interface software simplifies the programming of the entire line of common platform controls. This reduces the need for multiple software packages to interface with multiple controls. Control parameters can be programmed with a personal computer in the office using ProView NXG software. Programming files can then be loaded onto the control using a USB cable connection or through the front panel USB data port.

Control featuresControl security

The CL-7 voltage regulator control has multiple programmable security codes to limit control programming and viewing function access to authorized personnel. The CL-7 control is capable of supporting strong passwords containing letters (upper and lower case), numbers and symbols. The front panel Human-Machine Interface (HMI) includes a user-selected security code to access the settings. Plus, the ProView NXG interface software has its own security levels for multiple-user access.

Metering

The CL-7 control comes equipped with a full complement of metering capabilities, which include instantaneous, demand, demand peak, and energy metering. The control is capable of the following metering values and more:• Present tap position and percent regulation – per-phase and

average• Primary and secondary load and source voltage – per-phase and

average• Compensated voltage – per-phase and average• Real and reactive power – per-phase and total• Real and reactive currents – per-phase and average• Instantaneous frequency• Forward and reverse energy – per-phase basis and total• Power factor – per-phase and total• Total and time-period operations counters• Current and voltage harmonics per-phase

Duty cycle monitor (DCM)

DCM calculates the life used for each arcing surface contact on Eaton's Cooper Power series Quik-Drive tap-changers. The control uses metering values such as current, voltage, power factor, and tap position along with detailed data on the internal design of the voltage regulator to calculate the interrupting current and recovery voltage. This information is compared with actual test data for the appropriate Quik-Drive tap-changer to estimate contact wear. DCM works exclusively on voltage regulators equipped with Quik-Drive tap-changer.

Sequence of events (SOE) recorder

The SOE recorder is capable of capturing discrete events such as raise and lower operations, tap at neutral, mechanism failures and many other options. The SOE places an accurate time stamp and analog information on the events and stores them in non-volatile memory so they won’t be lost in the event that the control loses power. The SOE recorder is capable of maintaining up to 1000 events and can record up to 46 different event types.

Data profiler

A fully configurable data profiler is available which allows the user to collect information by sampling data at selectable intervals. These time-stamped values can then be viewed to determine weekly load profiles, daily harmonic disturbances, or hourly voltage fluctuations. The number of days of information the data profiler can provide depends upon configuration parameters. A Trend Time displays the days, hours and minutes of data that will be collected before the oldest data is overwritten.

Leader/follower feature

The CL-7 voltage regulator control can be operated as a member of an assigned operating group of up to three connected voltage regulators. When single-phase regulator controls are used, the Leader/Follower operation is dependent on a physical communications connection using the LoopShare Communications protocol between all members of the operating group. Enhanced Leader/Follower modes enable two types of group coordination. Leader/Follower modes include:

Lead-Phase – A connected regulators remain on the same tap position as the lead regulator;

Voltage Averaging – The average load voltage is determined and used as the basis for regulation.

Max Deviation – Regulators operate independently within a set number of steps.

Multi-phase operation

The CL-7 control with the optional multi-phase module is capable of operating up to three voltage regulators with the use of a single control. The voltage regulators can be set to operate independently or to utilize one of the Leader/Follower operating modes detailed above. A single control utilized in this configuration has several advantages over three individual controls:• Lower initial costs• Less inventory• Single access point communications• Three-phase metering• Simplified Leader/Follower (no communications required)• Fewer controls to program and maintain

Battery backup

The CL-7 voltage regulator control has two available battery backup options. A battery backup allows the control to remained powered during an outage and to maintain communication links.

Option 1 – An onboard 13 A/hour, 24 Vdc battery located in an auxiliary box attached to the main control box. A battery charger module is included with the regulator control.

Option 2 – Power the control with a 48 to 125 Vdc substation battery. For this option, auxiliary contacts are provided to connect the power source.

Auxiliary power options

The CL-7 control is able to provide auxiliary power for communications and other equipment. A 13.5 Vdc (Max output: 1.48 A, 1 second; Max Power: 14 W continuous, 20 W peak) option is available to meet the dc power requirements of most currently available communications equipment. If ac power is needed, a 120 Vac, 25 VA maximum load can be supplied using the PT winding of the regulator. If more power is required, optional auxiliary windings are can be added to provide 120 or 240 Vac (6 amp maximum) power.
